Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

333% Test Speedup

1. Normal Rails setup: 30 seconds for rake test
2. Using 1.9.3-falcon: 22 seconds
3. Using merged task w/ db reset: 16 seconds
4. Using merged task w/o db reset: 12 seconds
5. Using raw ruby execution: 9 seconds

You can run rake test:fast:db to get a merged run that resets your db. However, if you have clean tests that don't pollute the db between runs, you can just run rake test:fast and it will omit db:reset. This means your sequence numbers (under PostgreSQL, at least) may keep increasing, but if you tests against those I have other words for you.
